Uploading existing datasets of any significant size (“bulk imports”) to OpenStreetMap involves serious consideration, above that of ordinary updates and edits.I have done bulk imports to OSM before for UD/Newark Data. I used shp2osm (http://wiki.openstreetmap.org/wiki/Shp2osm) to convert from shapefile to osm format and then used JOSM (http://wiki.openstreetmap.org/wiki/JOSM) to compare to osm data, edit where needed, and upload the data/changes.Here…

I recently had a chance to test out ArcGIS Editor for OpenStreetMap (1.1 Beta3), an open source toolbox for interacting with OpenStreetMap (OSM). OSM, a popular open-source data repository, gained extra traction in the US after the Haitian Earthquake. This growth came from NGOs, and from some ArcGIS shops with open source leanings, who advocated…

I noticed a couple places where we have two polygons on top of each other (particularly for parking polygons) in the UD Campus Map. I just wanted to note, if you’re trying to modify an existing polygon on the map, make sure that you’re changing the existing shape, rather than adding a new one (otherwise…

Here’s how I imported, rendered, and served OSM data through mapnik, locally: 1. Do all downloads/installs … python (2.5 worked for me), postgres/postgis (8.3 worked), osm2pgsql, mapnik, rendering/mapnik utilities for OSM2. Follow info below on osm2pgsql3. Make sure mapnik bindings are registered with Python, run the demo under demopython to make sure mapnik works, here…

After getting mapnik installed and running I realized: 1. generate_tiles/generate_xml (and the rest of the render utilities) are really necessaryfor rendering OSM through mapnik. Therefore, you must download both mapnik through the mapnik site but also the mapnik OSM rendering tools which you can get through SVN at http://svn.openstreetmap.org/applications/rendering/mapnik/2. you must download world coastlines to…

Now that I’ve decided to locally render OSM data for the campus, I need to get the OSM data for the maximum extent of campus areas into a local database (both Mapnik and I prefer Postgres). I initially tried doing this by using OSM2PGSQL, but that ultimately failed … not completely sure why. Here are…

Update: Success! Was able to convert to OSM with Export_to_OSM.py, all was needed was to change some paths in the code. Uploads via JOSM using the Open, and Merge commands (I recommend also adding some tag so you can query these out later if you need to do anything with them), then Upload. Watch as…

So I am returning in the new year with a major task at hand: finish work on UD campus maps. As I recall, the major loose end from where I left off was the matter of the basemap — which resurrected old considerations about maintaining all layers on a cloud site (i.e. openstreetmaps) and send…
